Title: Light dome roof fixture flange - one piece, double sheathed, with sloping surface and foam insulation filled hollow
Inventor: RUEHL HANS F
IPC: E04D13/03
Filed: 1973-11-21
Abstract: The fixing flange is for light domes, or for the seating rings of light domes, or similar building components to be mounted on roof surfaces. It is made in one piece, with double walling, and is hollow. The base surface is flat, and one surface rises esp. in a stepped arrangement, from the edge towards the dome or other component. The hollow interior is filled with a filling material, esp. polyester foam or similar heat-insulating substance. The hollow fixing flange may be in one piece with the seating ring, with foamed plastic material common to both. The cross-section may be in a pointed wedge shape towards the edge. Ease of manufacture is combined with rigidly and good heat-insulating qualities.

Title: Material for use in mfr of footwear handbags etc - prepd by pre-strengthening a non-woven fabric, impregnating compacting, smoothing, calibrating and finishing
Inventor: SIEVERS KLAUS
IPC: D04H1/645
Filed: 1974-01-02
Abstract: Matl. used in mfr. of footwear, handbags and the like is produced by pre-strengthening a fleece, impregnating it, compacting with the aid of heated rollers, smoothing, calibrating, coagulating the binder, coating, passing through a water-bath, drying, and vulcanising or condensing. Cost-intensive operations e.g., needling, shrinking, and, in the case of mfr. of upholstery matl., splitting and buffing, are avoided. The prodt. is adequately strong, tensile, absorbent and vapour-permeable. Alternatively, the pr-strengthening step may be omitted. Coagulation may be by electrolysis.

Patent DE-2403509-A1 (DE)
Title: Sliding rod pump seal - has different rod diameter in middle portion thus varying pressure on O-ring
Inventor: KRIECHBAUM KARL DR
IPC: F16J15/32
Filed: 1974-01-25
Abstract: The seal is for use with a thrust rod sliding axially between two end positions and into a gas-tight housing containing e.g. sulphur hexafluoride, whose pressure differs from the ambient, having an O-ring of elastic material fitting in a groove in the housing. The diameter of the rod in its central portion is less than that at the ends, so that as the rod slides the O-ring is subjected to variable pressure. This pressure can be high in the end positions and lower in the middle, and the end portions of the rod can merge gradually into the central one. The rod can be honed to reduce friction. The design is particularly for flameproof switch contacts, and reduces friction and consequent heating of the O-ring during rod movement.

Insertable plugs are used, with an intermediate sheath made of soft material interposed between the plug and the sheath made of hard material, the intermediate one being pref. closed, wholly or partly, by a disc on the side facing the outer sheath, and equipped with attachments on the outside, which prevent slipping into the sheath and which spread elastically to simplify the removal process. Resistant connection is achieved with little regard being paid to dimensional accuracy, and with effective sealing.

Title: Three-point automatic car seat-belt and seat for child - with individual break-away anchorages for belts round abdomen ad thorax
Inventor: KOEPKE WILFRIED
IPC: B60R22/10
Filed: 1974-04-11
Abstract: This car safety-belt for a child provides two separate constraints. The abdominal belt, is held by an ordinary seat-belt fastener and whose length, although adjustable, does not alter with the child movement. It is intended to hold his hips fast. A pair of braces is attached to the abdominal belt, which cross over the child's chest and pass through eyelets attached at shoulder level to the child-seat and down to a spring-loaded spool at the back. These are intended to allow free movement for the upper part of the child's body. The respective anchorages of the belts have different break-away thresholds, lower for the abdominal belt (single, round a soft part of the body) than for the braces (double, possibly with a bib to spread the load, round the comparatively strong rib cage).

Title: Hot blast stove operating method - uses residual pressure from on-blast stove to supplement pressure to on-gas stove
Inventor: ONO YOSHIO
IPC: C21B9/10
Filed: 1974-04-22
Abstract: The method for operating a hot blast stove is characterised in that when intermittently operating a number of hot blast stoves each having a pressure supply valve, a cold blast valve, a stack valve, and hot blast valve and the like, the blast pressure within the hot blast stove at the time of transfer to the regeneration process after completion of the blast process is applied by means of the pressure supply valves to another hot blast stove on which the "on blast" state is going to start after completion of regeneration, thereby effectively utilising the residual pressure and heat.
